Abstract: A method and a system is provided for monitoring an area by a monitoring camera (1). A protected zone (5) is defined within the monitored area (2) and a suspicious object (9a, 9b) is detected as an object present both inside and outside the protected zone. A key position of the suspicious object is determined, and it is determined if the key position is inside or outside the protected zone (5). If the key position is outside the protected zone a first action is triggered.

Abstract: A pan-tilt camera is arranged to include a camera head, a stationary unit, an intermediate member arranged between the camera head and the stationary unit, a first rotary joint rotatably connecting the camera head to the intermediate member, and a second rotary joint, rotatably connecting the intermediate member to the stationary unit. A communication path is provided between the camera head and the stationary unit, including an optical waveguide arranged between the camera head and the stationary unit. The optical waveguide has a first end positioned at the first rotary joint to receive light from the camera head through the first rotary joint. The other end of the waveguide is positioned at the second rotary joint and is arranged to send light to the stationary unit through the second rotary joint.
